FUNCTION must accept string as single argument." (let ((start (if (use-region-p) (region-beginning) (point-min))) (end (if (use-region-p) (region-end) (point-max)))) (save-excursion (goto-char start) (while (<= (point) end) (funcall function) (forward-paragraph))))) (defun join-lines () "Joins lines of a paragraph." (interactive) (let ((fill-column (point-max))) (fill-paragraph nil))) (defun join-lines-buffer-or-region () "Join lines on all buffer." (interactive) (rcd-paragraphs-iterate 'join-lines)) However, there is some problem as it blocks, never ends, when I interrupt it with Ctrl-G then I see that lines have been joined in all of the buffer, but `while' loop was I guess still running.
